Good program. I especially liked the Dr. Folder program this company provided a short while ago.
Whilst visiting the GOTD site. I noticed an ad featuring Martin Lewis (moneysavingexpert).
You may be aware that Martin Lewis is suing Facebook because of ads alleging endorsement of certain products.
MARTIN LEWIS DOES NOT DO ADS !

John: Bit baffled why anyone sees ads on their computers nowadays. I can't remember the last time I did. What with free defenses such as NoScript, Adblock Plus, uBlock Origin and a host of others, there's no reason why someone's computer should be open to the planting of ads by all and sundry. I can't, however, speak for Facebook and Twitter monetized users, because they're in an exploitative world of their own making, nor for those who may complain about privacy violations but still use Google and Bing as search engines.

Had an older giveaway copy on my system. This installed right over it and remained a lifetime license without requiring entering the code or restarting. Thumbs up for a trivially simple update process.

No. No, I won't put this on my machine. A collection of "utilities" that are just for the most part (if not all) already built in to Windows. With the addition of some "Registry tools" that could seriously damage your machine if not used correctly. Way back in the day I used programs like this and spent many hours undoing the damage done by the vast majority of them. Then I wised up and LEARNED how to do what this does. Simple actually, and with the bonus of not tanking my machine. I urge you to do the same. Its not hard and you have the added bonus of KNOWING how YOUR machine works.

YL's website offers no help in describing why this should be installed. Vague promises of a speedier machine. Stock photo's of "their" people/business. No ultimate physical address except for US office location. Seems iffy to me. I'm almost positive this is a Chinese company but just TRY to find out. Now, that wouldn't automatically be a deal breaker for me but why the vagueness ?

Modern day snake oil imho. You want a speedier machine? Delete your cookies (built in to Windows and all browsers), Defrag your HDD (built in to Windows), Clean up your HDD (built in to Windows), delete unused programs (built in to Windows), turn off unnecessary/unwanted start up items (built in to Windows). If those don't help, buy more RAM and/or a newer faster HDD preferably a SSD. You cannot make a Volkswagen into a Porsche just by tuning it you know.

fares, huehuehue. I guess there is barely anyone taking your word for it. The only thing that dramatically speeds up anything is buying a new computer with better hardware. Otherwise we would still run on Pentium I with 256 MB RAM and a copy of WinUtilities, which would cost 5000$ per PC.
